Theoretical calculation of the amorphous alloy range of the Mg-Cu system

The enthalpy and free energy of competing phases--metastable solid solution, amorphous alloy and structurally simple compounds--of the Mg--Cu system were calculated by using a semi-empirical theory by Miedema and Niessen and by Lopez et al. which is based on thermodynamic considerations. These entha...

Zusammenfassung:	The enthalpy and free energy of competing phases--metastable solid solution, amorphous alloy and structurally simple compounds--of the Mg--Cu system were calculated by using a semi-empirical theory by Miedema and Niessen and by Lopez et al. which is based on thermodynamic considerations. These enthalpy and free energy diagrams reproduce well the range of complete amorphization caused by rapid quenching from the melt, as experimentally measured in a previous work by Sommer et al. .
